Full-field prediction for engineering-scale three-dimensional aircraft with multigrid-hierarchical learning

Researchers introduce MHLF, a multigrid-hierarchical deep learning framework that accelerates computational fluid dynamics simulations for full-scale 3D aircraft by 3-8x while maintaining high-fidelity accuracy across subsonic, transonic, and supersonic flight regimes. This breakthrough addresses a critical bottleneck in aerospace design by enabling practical full-flow-field prediction for engineering-scale aircraft, moving beyond previous limitations of 2D or simplified models.

An LLM-Orchestrated Agent for Directional-Coupler Design with Self-Consistent Eigenmode and FDTD Validation

Researchers present an LLM-based design agent that orchestrates the optimization of silicon-on-insulator directional couplers by coordinating eigenmode solvers and FDTD simulations without performing calculations itself. The agent achieved a 50/50 optical splitter with 0.498 cross-fraction accuracy against a 0.500 target, demonstrating effective human-AI collaboration in photonic device engineering.
